String Cloud and Domain Walls with Quark Matter in Lyra Geometry
ABSTRACT
We have constructed cosmological models for string cloud and domain walls coupled with quark matter in Lyra geometry. For this purpose we have solved the field equations using anisotropy feature of the universe, special law of variation for Hubble’s parameter proposed by Berman [78] which yields constant deceleration parameter; and time varying displacement field
. Further some properties of the obtained solutions are discussed.
